Establishment of a Traceability Chain in Metrology for Materials

Materials metrology is becoming an increasingly important international issue, with the worldwide efforts to realize a free trade agreement. The establishment of a traceability chain in materials metrology is, however, difficult because the measurement of materials properties is commonly procedure-dependent. This means that the establishment of a traceability chain in measurement of materials properties is not so straightforward as in physical measurement. In fact, three essential components, namely reference procedure, reference machine, and reference materials, are required to establish a traceability chain in materials metrology. In this paper, strategies to establish a traceability chain in metrology for materials are discussed to provide comparability amongst testing laboratories
